Dualnames, sorry if I'm being blunt, but this picture doesn't really work, and I think you're on the wrong track, basically.
Instead of decorating an empty space with arbitrary objects, you need to build your image, starting with the background and working your way up through layers.
Draw a sketch with the basic perspective outlines, then add furniture and clean up the image as you go. Also, you're being way too sloppy with lines and shapes - there's not a straight line in sight and it makes for a very jumbled impression.
